You will sit at the epicenter of our AI-first transformation, architecting agentic workflows that redefine marketing automation while simultaneously pioneering AI-assisted development practices that accelerate every team around you. This isn’t a role for someone who waits for a roadmap; it’s for a technical visionary who takes extreme ownership of the platform’s performance, scalability, and future trajectory. Whether you are embedding in a squad to unblock a complex AI integration or advising leadership on cross-cutting architectural debt, your influence will be the force multiplier that ensures our Kraków Hub remains a powerhouse of innovation. This is your opportunity to shape the direction of a world-class SaaS platform and see your contributions directly impact the way millions of users engage with intelligent automation On a typical day, you might: - Drive technical direction across multiple Kraków Hub teams, acting as a strategic advisor or embedding directly into squads when technical complexity demands a master-level touch. - Architect scalable agentic AI features, ensuring autonomous workflows and LLM integrations across platform subsystems—from CRM to email automation—are reliable and maintainable at scale. - Identify and resolve platform-wide bottlenecks with a whole-system perspective, optimizing everything from frontend rendering in React/Ember to deep backend logic in PHP and Python. - Champion AI-assisted engineering practices, leading the evaluation and adoption of cutting-edge tools (like Copilot, Cursor, or Devin) to transform how our internal teams build and test software. - Mentor and grow the next generation of talent, using pairing and code reviews to foster a culture of high ownership and technical rigor within the hub. - Bridge the gap between strategy and execution, articulating the basis for technical decisions to both engineers and leadership to balance business speed with long-term architectural health. The ideal candidate will bring: - 8+ years of hands-on software engineering experience, with a demonstrated track record of delivering high-impact results across multiple product areas or complex SaaS systems. - Multi-stack mastery with deep production experience in PHP and modern backend technologies, complemented by a strong competency in React or Ember. - Proven expertise in AI and Agentic development, including real-world experience designing autonomous agents, multi-agent orchestration, or deep LLM integrations. - The ability to act as a technical advisor, earning trust across the organization through sound judgment, clear architectural documentation, and a "whole-system" ownership mindset. - Experience in high-growth SaaS environments, ideally within the marketing automation or CRM domain, with a solid understanding of AWS, CI/CD, and observability at scale. - A working knowledge of Python for AI services and experience with data stores like MySQL, DynamoDB, or Redis at scale. - Fluency in English (B2 minimum) and the flexibility to collaborate effectively across time zones, specifically overlapping with US Central time. - Familiarity with emerging AI standards, such as the Model Context Protocol (MCP) or advanced AI coding assistants.
